Just to illustrate, let's say you've been accused of not only driving while under the influence; you've also been accused of causing injury to another person. In that case, you're probably facing a charge of vehicular assault. In Tennessee, for you to be convicted of DUI assault, a prosecutor will have to prove that alcohol -- and your being intoxicated by it -- was the proximate cause of the other person's injury.
However, even if you were under the influence of alcohol when a collision occurred, those circumstances alone are not sufficient to prove that your being intoxicated was the proximate cause of the injury. You should speak with a DUI defense attorney if you ever find yourself accused of vehicular assault.
In the meantime, consider a recent incident in Donelson.
